MAX9775, MAX9776 2 X 1.5W, Stereo Class D Audio Subsystem With DirectDrive Headphone Amplifier

The MAX9775 MAX9776 combine a high-efficiency Class D, stereo/mono Audio Power Amplifier with a mono DirectDrive" receiver Amplifier and a stereo DirectDrive Headphone Amplifier
Maxim's 3rd-generation, ultra-low-EMI, Class D Audio Power Amplifiers provide Class AB performance with Class D efficiency. The MAX9775 MAX9776 deliver 1.5W per channel into a 4 load from a 5V supply and offer efficiencies up to 79%. Active emissions limiting circuitry and spread-spectrum modulation greatly reduce EMI eliminating the need for output filtering found in traditional Class D devices.
The MAX9775 MAX9776 utilize a fully differential architecture, a full-bridged output, and comprehensive click-and-pop suppression. A 3D stereo enhancement function allows the MAX9775 to widen the stereo sound field immersing the listener in a cleaner, richer sound experience than typically found in portable applications. The devices utilize a flexible, user-defined mixer architecture that includes an input mixer, Volume Control and output mixer. All control is do 546 ne through IC.
The mono receiver Amplifier and stereo Headphone Amplifier use Maxim's patented DirectDrive architecture that produces a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, space, and component height.
The MAX9775 is available in a 36-bump UCSP" (3mm x 3mm) package. The MAX9776 is available in a 32-pin TQFN (5mm x 5mm) or a 36-bump UCSP (3mm x 3mm) package. Both devices are specified over the extended -40C to +85C temperature range.
